本试验方法涵盖了一种程序，用于测量低克数或高柔韧性，或两者兼有，且弯曲刚度在0到10泰伯刚度单位范围内的纸张的抗弯曲性。该试验用于确定使38 mm（1.5 in.）自由端偏转所需的弯矩施加10 mm（0.39 in.）荷载时，从中心线垂直夹紧的宽试样15远离钳子。抗弯能力由弯矩计算得出。本试验方法中使用的仪器与第6.2.4节所述修改配置中使用的TAPPI T 489纸和纸板抗弯（刚度）（基本配置中的泰伯型测试仪）中所述的仪器相同。仪器的准备。0-10单位测试范围将刻度指示放大十倍，以便在摆锤的标准范围（0）以下测试柔性材料- 100泰伯刚度单位）。据报告，使用本试验方法中所述的泰伯式测试仪获得的试验结果与使用TAPPI T 489获得的结果相差40%，且在规定使用TAPPI T 489的情况下，不得使用本试验方法。测量弯曲阻力的其他程序包括TAPPI T 535纸张和纸板的弯曲刚度（共振长度法）；TAPPI T 543纸的抗弯曲性（Gurley型测试仪）；TAPPI T 556单点弯曲法测定纸张和纸板的抗弯曲性；和TAPPI T 836弯曲刚度，四点法。TAPPI T 535已被归类为经典方法。

This test method covers a procedure used to measure the resistance to bending of papers which are of low grammage, or high flexibility, or both, and which exhibit bending stiffness in the range of 0 to 10 Taber stiffness units.This test is used to determine the bending moment required to deflect the free end of a 38 mm (1.5 in.) wide vertically clamped specimen 15 from its center line when the load is applied 10 mm (0.39 in.) away from the clamp. The resistance to bending is calculated from the bending moment.The instrument used in this test method is identical to that described in TAPPI T 489 BendingResistance (stiffness) of Paper and Paperboard (Taber-type tester in basic configuration), used in the modified configuration described in section 6.2.4. Preparation of Apparatus. The 0-10 unit test range magnifies the scale indication ten times so that flexible materials can be tested below the standard range of the pendulum (0-100 Taber stiffness units).Test results obtained using the Taber-Type Tester as described in this test method have been reported to be as much as 40% different from those obtained using TAPPI T 489, and this test method must not be used where TAPPI T 489 is specified.Other procedures for measuring bending resistance include TAPPI T 535 Bending Stiffness of Paper and Paperboard (Resonance Length Method); TAPPI T 543 Bending Resistance of Paper (Gurley-Type Tester); TAPPI T 556 Bending Resistance of Paper and Paperboard by Single-Point Bending Method; and TAPPI T 836 Bending Stiffness, Four Point Method. TAPPI T 535 has been classified as a Classical Method.
